BURNER FOR KEROSENE vAND THE LIKE.

Application filed November 14,1921, Serial' No. 514,869.

To all whom it may concern."

Be it known that I, DUNcAN htlAODONALD, citizen of the United States, and residing in the town of Garfield, in the county of Mahoning and State of Ohio, have invented or discovered a new, useful, and Improved BurnerforKerosene and the like, of which the following is a specification. My invention consists in a new and improvedburner for kerosene and the like.

lVhile applicable to other uses, my improved burner is more'particularly intended for use with steam-driven motor vehicles.

The object which I have in view is the provision of a burner which will possess an increased flame and heating capacity for a given area, which will provide for a uniform distribution ofthe fuel and therefore produce a uniform flame throughout its entire surface, which will not unduly expand or its efficiency become impaired by expansion, and which will not blow backinto the gas chamber.

lVith these purposes in View, I have provided a burner whose flame surface is characterized by parallel series of gas slots, each series being multiple in character and adjacent series beingseparated by solid or unslotted portions which may be provided with a covering of asbestos or other refractory material. Thus I have shown, as the preferred form of my improved burner, the fiamesurface formed by a plurality of metal channels having their troughs filled with asbestos and spaced apart by means of spacer I bars between which are formed the gas slots.

' To provide the necessary flexibility to take up'excess expansion, which might otherwise distort the burner surface and impair the efiiciency of the burner, said spacer bars are-assembled in staggered relation and their interlacing ends are pivotally connected together and to the'flanges of the adjacent channels, the holes through which the pivot members pass fitting loosely enough take up considerable expansion.

Other novel features of construction and of arrangement of parts will appear from the following description.

In the accompanying drawings, which are, however, merely intended to illustrate a practical embodiment of the principles of my invention without limiting the scope of the latter to the construction shown, Fig. 1 is a top plan view of a burner constructed in accordance with the principles of my. invention; Fig. 2 isa sectional view of the same taken along the line 11-11 in Fig. 1;

Fig. 3 is aside elevation of the burner, the

bars may be used, as may be desired. The

rows of bars comprising each series of rows are assembled in staggered relation with their ends interlacing and the interlacing ends of the bars are pivoted together and to the lateral flanges of the adjacent channels, by means of the pivot rivets or bolts 1, which extend through alined holes in the bars and flanges, said holes being preferably loosely fitting to provide for expansion.

The mannerof assembling the spacer bars forms the gas slots 2 which are thus disposed in parallel rows, the slots in one row being in staggered relation to the slots in the adj acent rows. The outer extremities of the end slots are closed by small spacer blocks 3 through which the rivets 1 pass. I C is the gas chamber, preferably formed by a convened metal wall 4 whose top edges are brought up on the outside of the end channels A and turned over the flanges of the same, as shown 5 in Fig. 2, and riveted to said flanges. The ends of the be provided at more or less frequent intervals and at each end they are used for the attachment. of the end walls 6 of the gas chamber.

, The channel members support and stiffen the burner structure, and the height of I their flanges determine the depth of the gas slots which must be sufficient to give the proper velocity oftravel of the gas. -The asbestos protects the metal channels and prevents the penetration of heat sufiicient to cause preignition in the gas chamber.

This elimination .of heating .suflicient to cause preignition is also contributed to by the Velocity of the gas passing from the gas chamber through the slots.

In operation the gasified fuel is supplied I evenly throughout the burner surface,-the

depth of the slots, dictated by the height of the channel flanges and the bars, being suflicient to give the necessary draft in the gas openingswhich prevents blow backs or the i instantaneously,

1 sure ignition of the fuel in the gas chamber.

The result is an even, uniformly distributed fire which isreadily lit by the pilot lightqor other ignition means, responding and thus insuring the prompt provision .of steam pressure which is a cardinal necessity in steam-driven motor. vehicles. Also the fuel supply maybe nicely regulated to produce the steam presdes'ired without extinguishing the flame over a portion of the burneras is so frequently the case in many steam driven motor vehicles; V

, Although. for the sake of clearness, I

have minutelyidescribed the embodiment oftheprinciples of my invention illustrated in the drandngs, I do not wish to limit myself thereby, but claim broad1y .1. A burner of the character described composed of a chamber adapted to receive the fuel in a gasified state and provided wlth a burner face composed of a plural ty .of impervious members in parallel and spaced relation, and a plurality of spacer bars interposed between adjacent members in such a manner as to form gas slots, the

said bars beingsecured in place at each end by pivotal attachment to provide flexibility for, expansion. 7

a burner face composed of a plurality of impervious members in parallel and spaced relation, and a plurality of spacer bars interposed between adjacent members, said bars being assembled in staggered relation, with interlacing ends, to form gas slots.

4. A burner of the character described composed of a chamber adaptedto receive the fuel in a gasified state and provided with a burner face composed of a plurality of impervious members in parallel and spaced relation, and aplurality of spacer bars interposed between adjacent members, said bars being assembled in staggered relation, with interlacing ends, to form gas slots, and the ends of said bars being pivotally connected together. I

5. A burner of the character described composed ofa chamber adapted to receive the fuel in a gasified state and provided with a burner face composed of a plurality of impervious members in parallel and spaced relation, and a plurality of spacer bars interposed between adjacent members, said bars being assembled in staggered relation, with interlacing ends, to form gas slots, and the ends. of said barsbeing pivotally connected together and to said members.

6. A burner of the character described composed of a chamber adapted to receive the fuel in a gasified state and provided with a burner face composed of a plurality of channel members disposed in parallel and spaced relation, and a plurality of spacer bars mounted between adjacent channel members, said spacer bars being disposed instaggered relation so as to form gas slots.

7. A burner of the character described composed of a chamber adapted to receive the fuel in a gasified state and provided with. a burner face composed of a plurality of channelmembers disposed in paralleland spaced relation, and a plurality of spacer bars mounted between adjacent channel members, said spacer bars being disposed in staggered relation, with interlacing ends, to form gas slots, and the ends ofsaid. bars being pivotally connected together. I

8. A burner of the character described composed of a chamber adapted to. receive the fuel in a gasified state and provided with a burner face composed of aplurality of channel members disposed in parallel and spaced relation, and a plurality of spacer bars mounted between adjacent channel members, said spacer bars being disposed in staggered relation, With interlacing ends, to form gas slots, and the ends of said bars being pivotally connected together and to said channel members.

9. A burner of the character described composed of a. chamber adapted to receive the fuel in a gasified state and provided with a burner face composed of a plurality of channel members disposed in parallel and spaced relation, a filling of refractory material for said channel members, and spacer members interposed between adjacent channel members, said spacer members being in staggered relation with interlacing ends, and being supported in position by the pivotal connection of their interlacing ends to said channel members.
